00:00C'est parti !

00:30...by Benoit Mandelbrot.

00:32My work has consisted in one major good idea,

00:36the fractal geometry of nature.

00:38What Mandelbrot has done,

00:40he has made some sort of new geometry

00:42which made us able to describe the nature

00:45as we see it around us.

00:47So it made people think in a different way.

00:50Fractal geometry is a new language

00:52that has completely revolutionized

00:54the way that scientists look at and explore our world.

00:59Fractal geometry describes the apparently random forms

01:03that exist in nature like rivers, trees, the human body.

01:07To do science, you must describe nature.

01:10The language can be just words,

01:12it can be formulas, it can be shapes, many things.

01:16Fractal geometry provides the language.

01:18But he picked it up and saw immediately that nature

01:22for some reason has chosen this particular feature

01:26as a worthwhile technical help

01:30in accomplishing whatever nature tries to accomplish.

01:33And Benoit saw that very clearly.

01:36and he seems to have known it all

01:39when he became aware of how these different strands,

01:43how these different sources were playing together in a new way.

01:46That makes him unique.

01:48There is a very strong resemblance

01:50between the path of my life, my life orbit and my work.

01:55On any number of occasions in the past 30 years,

01:59Benoit has been first obviously wrong

02:03and then viewed as well sort of right

02:07and then people would finally say,

02:08well we knew that all along.

02:10There are people for example who think

02:12a mammal boat should get the Nobel Prize

02:14and I agree with that.

02:16Long ago as a young man,

02:18I had this romantic notion

02:20that what I would like to do

02:22was to find some aspects of the world around us

02:25which others would have not thought of.

02:29This hope has filled my whole life.

02:31In that sense, I feel extremely fortunate.

02:35He's a visionary.

02:36Now we can see fractals everywhere.

02:39every have.
